Seagull and interwar presence missions

The Seagull section gives the Walrus a direct predecessor and explains the operating habits built during the 1920s and 1930s. Only thirty-four were built, but they provided practical experience after development from the earlier Supermarine Seal. The type's connection to the Japanese Naval Air Service through the Sempill Mission also shows how British naval-aviation expertise traveled abroad. Royal Navy cruisers and the carrier Eagle then used Seagulls as mobile bases for maritime patrol, presence, and counter-piracy work. The comparison with the 1972 Buccaneer deployment over Belize shows the lasting logic: an aircraft overhead could make naval power visible well beyond a port visit by its parent ship.
